How long does it take for hair to regrow after telogen effluvium? (Photo)

Question

I had a big hair shed about 6-7 months ago that my doctor feels is related to a flu (7 days of high fever). I have never experienced this before so unlikely that it is chronic. I now have a " halo" of regrowth about 4 inches long but hair still feels thin. How does hair normally recover from a TE? Does hair return in stages or all at once? Will rogaine give it a boost?

If you are losing hair and want treatment options you should schedule a consultation with a doctor to confirm a diagnosis.Telogen effluvium may take 6 to 12 months (in general) to recover.

Jeff Donovan, MD, PhD · Answer

Hair regrow starts quickly after the shedding occurs but shedding continues even as the hair is regrowing. Hair grows in stages- some at month 1, some at 2 some at 3 because hair is still losing at month 1, month 2 and month 3. It does not all fall out at once and it does not all grow back at once. It takes 12 -14 months to recover (if a TE is all a patient has).

William Rassman, MD (retired) · Answer

TE often reverses once a hair cycle has taken it course, usually 6-8 months, but as our hair grows differently and at different rates in each area of the scalp, it might take up to two years for this to reverse. It have seen TE reverse in as short a time as 6 months and as long a time as 3 years, reflecting the total hair cycle in the person.
